The SQ 50 LED road luminaire has been designed to modernise existing installations with high energy efficiency and to supply standard-compliant lighting for new installations. The familiar, contemporary and functional housing accommodates a gear tray with state-of-the-art LED technology and precisely matched optical systems.
This principle ensures that with the supplementing of existing systems with efficient SQ 50 LED light points, the harmonious overall appearance of the installation is maintained. The LED luminaire can be individually set according to needs via the microprocessor-controlled LED operating electronics with the performance packages 'Plus' (with Siteco® Service Box) and 'Premium' (with Street Light Control).
Thanks to Siteco gear tray technology the LED module of the SQ 50 LED luminaires is replaceable, and an upgrade to future, higher-performance LED modules is thus easily implemented.

• ideal for expanding existing installations: the visual appearance of the road is maintained
• innovative LED gear tray technology with precisely matched lenses and reflectors for energy-efficient lighting
• LED insert for standardised lighting of roads according to DIN EN 13201, for wide luminaire spacing with uniform illumination
• optical enclosure of white glass with excellent transmission factor, structured and reflection-reduced for excellent glare elimination and very good homogeneity
• constant luminous flux control (Plus version) for precise and highly efficient road lighting
• long system service life (> 50,000 hrs)
• highly simple mounting and maintenance: modular gear tray concept, can be simply replaced for future upgrading of SQ 50 LED versions
• convenient one-hand lever catch
• universal mounting for post-top and side-entry mounting via pivotable mast clamping plate
• high quality, durable housing material of diecast aluminium
• flat optical enclosure for increased vandal protection
• high quality four-level sealing system with air-permeable membrane for optimal pressure equalisation
• safe IP66 protection rating for complete luminaire

Two-part luminaire housing consisting of frame and canopy (can be opened upwards) | frame, mast clamping plate, canopy and easy-access one-hand lever catch of diecast aluminium with extremely weather-resistant coating: frame metallic grey (RAL 9006), canopy aluminium grey (RAL 9007) | all-round bi-component EPDM sealing with labyrinth function | flat optical cover of toughened safety glass (ESG) | pivotable mast clamping plate flush-integrated in frame, for post-top and side-entry mounting; 0° inclination with post-top mounting, with offset mast spigot with side-entry mounting | pressure equalisation system with air-permeable membrane for condensation avoidance in the housing | insulation class: II | protection rating: IP66 for complete luminaire (dustproof and water-jet proof)

Canopy opened without tools, can be folded upwards; with automatic all-pole power disconnection | LED modules and all electric components on removable gear tray
Basic performance package: LED module with 3-pole connection terminal, max. 2.5mm² (2-pole for mains supply + 1-pole for 230V control voltage for power reduction) | control signal: U_St= 230V --> 100% luminous flux; U_St= 0V --> approx. 50% luminous flux
Plus performance package: LED module with 5-pole connection terminal, max. 2.5mm² (2-pole for mains supply + 1-pole for 230V control voltage for power reduction + 2-pole for Siteco® Digital Interface (SDI) for parameterising of the luminaire with the Servicebox and integration into the digital control system
Premium performance package: LED module with 2-pole connection terminal, max. 2.5mm² (control and monitoring of the luminaire from a central control point without supplementary control wires; data transmission according to standardized LON protocol)

Wide light distribution for standard-compliant lighting according to DIN EN 13201 | excellent glare reduction and high homogeneity with minimised light immission via LEDs with oval attachment lens and additional light control via lateral reflectors and structured, reflection-reduced flat cover panel | high level of system efficiency via optimised light distribution and large luminaire spacings

• residential areas, side streets, residential and collector roads
• for large light-point spacing of 25…32m
